4773	Simulation from OMEdit fails for Cpp runtime under Windows	Rüdiger Franke	Adeel Asghar	"The following model simulates under Linux and from command line under Windows.

{{{#!mo
model TableTest
  extends Modelica.Blocks.Tables.CombiTable2D(
      table = [0.0,   1.0,   2.0,   3.0;
               1.0,   1.0,   3.0,   5.0;
               2.0,   2.0,   4.0,   6.0]);
  annotation(uses(Modelica(version=""3.2.2"")));
end TableTest;
}}}

The 32bit Windows release of OpenModelica produces the following error when attempting to simulate the model from OMEdit:

{{{
C:/Users/Someone/AppData/Local/Temp/OpenModelica/OMEdit/TableTest/TableTest.exe -port=64319 -logFormat=xmltcp -override=startTime=0,stopTime=1,stepSize=0.002,tolerance=1e-6,solver=dassl,outputFormat=mat,variableFilter=.* -r=C:/Users/Someone/AppData/Local/Temp/OpenModelica/OMEdit/TableTest/TableTest_res.mat -w -lv=LOG_STATS -inputPath=C:/Users/Someone/AppData/Local/Temp/OpenModelica/OMEdit/TableTest -outputPath=C:/Users/Someone/AppData/Local/Temp/OpenModelica/OMEdit/TableTest

{{{

}}}

Following observations are made:
- the simulation does not always fail. Press Re-Simulate to see the crash then
- the simulation runs from Tools -> OpenModelica Command Prompt (when omitting the `-port` option)
- when called from OMEdit, the simulator builds up a lot of memory for about 1 second, before it exits
- the Linux version warns about unknown `-inputPath` and `-outputPath` options -- these warnings don't appear under Windows

Looks like a newly introduced problem (e.g. caused by changed logging, new subdirectories in OMEdit folder, specifics of Windows build, ...)."	defect	new	blocker	1.13.0	OMEdit	v1.13.0-dev-nightly			Niklas Worschech Adrian Pop
